Attachable backpack apparatus

ABSTRACT

An attachable backpack apparatus for reducing sweat and heat is described herein. The attachable backpack apparatus may comprise one or more of a body, a backpack attachment component, and/or other components. The backpack attachment component is configured to removably engage with carrying straps of a backpack a forming an as-used position of the attachable backpack apparatus. The as-used position of the attachable backpack apparatus causes the body to be disposed at or near a lower portion of the backpack. The attachable backpack apparatus may separate a portion of the backpack from a portion of the user&#39;s back. Contact between the backpack and the user is therein reduced, while maintaining the traditional strap-based engagement of the backpack to the user and without adversely modifying the backpack&#39;s structure. The separation may create a channel between the backpack and the user to allow air to pass through.

FIELD OF THE DISCLOSURE

This disclosure relates to an attachable backpack apparatus, in particular, an apparatus that reduces heat and sweat experienced by a user during use of a backpack.

BACKGROUND

Backpacks are widely used by people who travel, go to school, for leisure, for business, and any purpose to store and carry essentials. A backpack, in general, is a bag with compartments that have shoulders straps and is worn on the back of a person. Most backpacks lay flat against a person's back when worn.

SUMMARY

One or more aspects of the present disclosure relate to an attachable backpack apparatus to reduce head and sweat. If worn for a long period of time, backpacks generally cause heat to be generated, which becomes trapped between the person's back and the backpack that can result in an uncomfortable sweat. The sweat is retained on the clothing of the person's back and absorbed into the backpack. Additionally, having a wet area around the back of a person's shirt is visually unappealing. This leads a person to carry the backpack over one shoulder. Although this may temporarily resolve the heat and sweat problem, carrying a backpack in this position may disrupt proper posture and can lead to back irritation.

One or more implementations of the present disclosure propose an apparatus in the form of, but not limit to a cylindrical tube made of soft foam (e.g., polyurethane foam), wrapped in textile with a strap/loop at each end. The end of each strap attaches to the backpack's lower part of the shoulder straps and may be secured with detachable fasteners. When the backpack is worn, the apparatus may be positioned in between a portion of the user's back and a portion of the backpack. The apparatus may separate the portion of the backpack from the portion of the user's back. Contact between the backpack and the user is therein reduced, while maintaining the traditional strap-based engagement of the backpack to the user and without adversely modifying the backpack's structure. The separation may create a channel between the backpack and the user to allow air to pass through, thereby reducing heat that causes sweat.

These and other features, and characteristics of the present technology, as well as the methods of operation and functions of the related elements of structure and the combination of parts and economies of manufacture, will become more apparent upon consideration of the following description and the appended claims with reference to the accompanying drawings, all of which form a part of this specification, wherein like reference numerals designate corresponding parts in the various figures.
